Specification of Letters Patent.

Patented Oct. 17', 1905.

Application filed April 8, 1905. Serial No. 254,568-

To all w/mm it nuty concern:

Be it known that I, SAVERIO PIERRO, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful improvements in AdjustableHorizontal Bars; and I do hereby declare the following to bea full,clear, and exactdescription of the invention, such as will enable othersskilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in horizontal bars, and hasparticular reference to that class of exercising paraphernalia adaptedfor outdoor and home use.

The object of my invention is to provide a device of this characterwhich combines stability, simplicity, and ease of erection in anyprivate house or public place without the use of cumbersome tools orinstruments, and, on the other hand, to provide a bar of this class theindividual elements of which may be readily and speedily disassociatedand the entire apparatus taken down and stored away without anylaborious expenditure of efi ort.

it consists, primarily, in simple suspending means, if in a house, fromthe lintel of a door, and suitable mechanism for clamping the device atany desired height onto the jamb of the door, therefore preventing anyoscillatory motion of the device when placed in position for use.

It consists, furthermore, in such features,

details of construction, and combination of parts as will appear morefully from the accompanying drawings and then more particularly pointedout in the claims.

Referring to the drawings, Figure 1 is a front elevation of the entireapparatus in position for use; Fig. 2, a vertical section of the meansfor clamping the device to thelintel of a door; Fig. 3, a longitudinalsection of the means for supporting the bar, and Fig. 41 adetailsectional view of the mechanism for permitting of the verticaladjustment of the bar.

Referring in detail to the drawings, 1 is the lintel of the door, havingon each side the usual molding, upon which rests the two sets ofgripping-hooks 2. These hooks or clamping-jaws are located within aU-shaped frame or bracket 3 and are pivotally mounted therein upon aplate 1, resting upon the bottom of the frame and being firmly securedin place by bolts 5, extending through the bottom of the frame andbase-plate 4:. These bolts 5 also serve to secure two depending ears 6,which are arranged to clampthe suspendingrods 8 and 9 from the lintel ofthe door. The gripping-jaws 2, located within the U-shaped frame, areactuated by one or more thumbscrews 7, which extend through the uprightarms of the frame and impinge against said jaws. In this manner the jawsare tightly held in place and are prevented from accidentally releasingtheir grip or their hold on the vertical supporting-bar above. The rodswhich are suspended by the ears 6 are joined at or about their extremityto a turnbuckle 16. For this purpose the correspondingears of each ofthese rods are provided with screwthreads which engage thescrew-threaded By means of this sockets of the turnbuckle. device theentire apparatus when not already secured in the desired position can beeither raised or lowered by simply revolving the buckle in eitherdirection, as the case'rnay be, in order to change the height of thehorizontal bar.

The lower rods 9 have loosely mounted in their extremity in the mannerdesired carrying means for the horizontal bar to be em-- ployed, whichin this instance consists of an inverted-U-shaped frame 10, which isarranged to snugly fit over the boss 11, Fig. 3, which carries andsupports the horizontal bar 12. This boss is fastened to a suitableclamping member or frame 13, said frame being adapted to snugly engagethe jamb of the door upon which it is intended to be fitted and thensecured in place by a set or thumb screw 15, extending through one ofits walls. In this manner it is obvious that any oscillatory motion ofthe horizontal bar when in use by the exerciser is impossible, and it islikewise to be seen that by releasing the thumb-screw 15 the entirehorizontal bar 12,with its attendant fastening means, may be verticallyadjusted by manipulation of the turnbuckle.

By providing one of the ends of each of the rods 8 and 9,whichconstitute a sectional suspending member, with screw-threads and fittingthem into a turnbuckle the horizontal bar 12 may be readily adjusted toany height.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a device of the character described, the combination of a pair ofsuspending members, movable jaws secured to the upper ends of saidsuspending member, means for adjusting said jaws, a clamping membercarried by the lower end of each of said suspending members, and ahorizontal bar connected to said suspending and clamping members.

2. In adevice of the character described, the combination withadjustable, sectional supporting members, clamping-jaws secured to oneend of each of said members, a clamping member secured to the oppositeend of each of said members, and a horizontal bar interposed between andcarried by said sectional members.

3. A device of the character described, comprising a pair ofsubstantially parallel suspending members, each member comprising rods,a turnbuckle connecting said rods, ears secured to the upper end of eachof said members, a substantially U-shaped frame secured to the ears ofeach of said members, a plate carried by said U-shaped frame,clampingjaws pivotally mounted upon said plate, means for adjusting saidjaws, ears secured to the lower end of each of said suspending members,an inverted, substantially U shaped frame carried by the ears of each ofsaid suspending members, a horizontal clamping member carried by each ofthe inverted, substantially U-shaped frames, each clamping memberprovided with a boss positioned between said substantially U-shapedframes, and a horizontal bar supported by the bosses of said clampingmembers.

4. In a device of the character described, the combination withsuspending means, of pivotally-mounted clamping-jaws engaging saidsuspending means, means for securing said aws in an adjusted position,and a hori' zontal bar carried by said suspending means.

5. In a device of the character described, the combination withsuspending means, of a horizontal bar carried by said suspending means,clamping means engaging the ends of said horizontal bars, and adjustablejaws engaging said suspending means.

6. In a device of the character described, the combination of adjustableclampingjaws, means for securing said jaws in a fixed position,suspending means carried by said jaws, a bar carried by said suspendingmeans, and means for preventing said bar from swmgmg.

7. In a device of the character described, the combination of sectional,suspending members, means for adjusting the sections of said suspendingmembers, clamping means carried by the ends of each of said suspendingmembers, and a bar carried by said suspending members.

8. In a device of the character described, the combination ofadjustable, suspending members, clamping means secured near each end ofsaid members, and a bar carried by said suspending members.

9. In a device of the character described, the combination with aplurality of suspending members, clamping means engaging the ends ofeach of said suspending members, and a bar carried by said suspendingmembers.

10. In a device of the character described, the combination with aframe, of a horizontal bar positioned between said frame, means forvertically adjusting said bar within said frame, and clamping meanssecured upon said frame near each end of said bar for preventingswinging movement thereof, said clamping means comprising members partlysurrounding portions of said frames.

11. In a device of the character described, the combination with aframe, of clamping means engaging the upper portion of said frame,adjustable, suspending means carried by said clamping means, a barcarried by said suspending means, and means for preventing swingingmovement of said bar.

In testimony whereof I affix my signature in presence of two witnesses.
